The complete CESL program has nine levels, the lowest four involving an individually-based curricular format (see below). The number of levels needed to complete the program is based on initial placement. All students receive in all levels 20 hours per week of intensive English language instruction. At each level above Learning Center (see below), all language skills are treated in a core class meeting 10 hours per week. Additional instruction is provided at each level in two 5-hour classes that differ by level, as indicated below.<br><br>Instruction for the lowest four levels takes place in a Learning Center, which involves students combined in a single cohort studying at various stages of the beginning and elementary stages. The instructor helps each student attain the learning objectives they need to master before graduating to the Advanced English 1 level. Each student progresses at their own speed.
